Compact Tube Furnaces PORTABL GREJAC GREALAKA

RD 30/200/11 - RD 30/200/13

The RD product line furnaces convince with their unbeatable price-performance ratio, very compact outer dimensions and their low weight. These all-rounders are equipped with a working tube which also serves as support for the heating wires. Thus, the working tube is part of the furnace heating which has the advantage that the furnaces achieve very high heat-up rates. The furnaces can be supplied for 1100 °C or 1300 °C. Both models are designed for horizontal application. If the customer requires protective gas atmosphere, a separate working tube incl. gas supply system 1, e.g. made of quartz glass, must be inserted in the working tube.

• Tmax 1100 °C or 1300 °C
• Housing made of sheets of textured stainless steel
• Inner diameter of the tube: 30 mm, heated length: 200 mm
• Working tube made of C 530 material including two fiber plugs as standard
• Thermocouple type K (1100 °C) or type S (1300 °C)
• Solid state relays provide for low-noise operation of the heating
• Heating wires wound directly around the working tube resulting in very fast heat-up rates

Additional equipment

• Over-temperature limiter with adjustable shut-off temperature for thermal protection class 2 according to EN 60519-2 as over-temperature protection for furnace and load
• Gas supply system for non-flammable protective or reactive gas
